Abstract (en)

[origin: EP0326358A2] A machine for manufacturing a stud and eyelet assembly in a web (27) that moves continuously between the eyelet die wheel (41) and the stud die wheel (42). The eyelet magazine (55) continually supplies eyelets from an eyelet hopper to the eyelet transfer wheel (53), which in turn continually supplies the eyelets to the eyelet die wheel (41). Likewise, the stud magazine (56) continually supplies studs from a stud hopper to the stud transfer wheel (54), which in turn continually supplies studs to the stud die wheel (42). The eyelet or stud is held on the die (45, 46) of the die wheel (41, 42) and the stripper (57, 58) of the transfer wheel (53, 54) by a vacuum (60). The vacuum (60) is applied from a vacuum source through ports (81, 82, 83, 84) in each wheel to the die (45, 46) or stripper (57, 58) interface with the eyelet or stud. The vacuum in a transfer wheel operates from the point it receives an eyelet or stud from the magazine until the point where the eyelet or stud in transferred to the die wheel (42). Similarly, the vacuum in a die wheel operates from the point it receives the eyelet or stud from the transfer wheel to the time the eyelet and stud are assembled in the web at the nip (43). A single drive input rotates a gear (106) at the base of one wheel, which in turn synchronously rotates the other wheels through a gear train at the wheel bases.
